Wireless Power Transmission Circuit | Easiest

Hi, guys, this article is based on a wireless power transmission circuit. This circuit explains how you can transfer dc input from one coil to another without any core or contact between. The transmission of AC input power between the two coils is pretty much easier and convenient as compared to dc. This circuit also […]
